In this article, an efficient dual‐band rectenna making use of the newly proposed symmetrical rectifying circuit working at the frequency of 1.8 and 2.45 GHz, is proposed. The proposed dual‐band rectifying circuit is combined with an array of compact wideband planar monopole modified circular slot antenna in order to facilitate the efficient rectenna design. The rectifying circuit employs symmetrical matching network in addition to the symmetrical rectifier thereby facilitating the suppression of the odd order harmonics. This eventually results into the higher output voltage as compared to the conventional rectifier circuits. Moreover, the dual‐band topology of the proposed rectenna increases the overall voltage by harvesting energy from two independent RF sources. The measured results of the fabricated structure show that the maximum RF to dc conversion efficiency of the proposed rectifier circuit reaches up to 70% at 9 dBm input RF power. From application point of view, the proposed rectenna circuit is tested to extract the RF energy from 1.8 GHz cellular and 2.45 GHz Wi‐Fi bands to energize a low‐power LED. The overall rectenna structure is reasonably compact providing good performance, which can potentially be employed for efficient wireless power transmission system.

Abstract-With the increase of low power devices, the design of a compact and efficient rectenna is essential for supplying energy to the devices. This paper presents a compact rectenna for high efficient WiFi energy harvesting. A novel fractal geometry is introduced in the design of antenna for miniaturization, and the ability to harvest WiFi energy is enhanced due to its characteristics of self-similarity and space filling. Besides, a single stub matching network is designed to achieve high conversion efficiency with a relatively low input power ranging from −20 dBm to 0 dBm. Simulation and experiments have been carried out. The results show that the proposed antenna features a good characteristic of reflection coefficient and realized gain at WiFi band. The highest RF to DC conversion efficiency of the rectenna is up to 52% at 2.45 GHz with the input power of 0 dBm. This study demonstrates that the proposed rectenna can be applied to a range of low power electronic applications.

“…It is an effective approach to provide continuous power to electronic devices without battery requirements. [1][2][3] Generally, rectifying antenna (rectenna) is a crucial factor in RF energy harvest applications. Most of the rectennas focus on single frequency with a narrow band as RF to DC conversion efficiency can be enhanced at high-input power.…”

In this article, a compact broadband rectifying antenna (rectenna) is proposed to harvest RF energy. A novel Vivaldi antenna is presented and an efficient rectifier with a single stub matching network is designed. Simulation and experiment have been performed and a good convergence is observed between the simulated and measured results. The experimental results show that the antenna features a broad bandwidth from 2.3 GHz to 2.85 GHz and the maximum conversion efficiency of the rectifier is up to 68% at 0 dBm. The maximum conversion efficiency and output voltage of the proposed rectenna are 58% and 1.6 V at 2.45 GHz under the input power of 0 dBm.
